Optical fibre transmits one terabit per second

Optical fibre transmits one terabit per second
  Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich (TUM) have achieved unprecedented transmission capacity and spectral efficiency in an optical communications field trial with a modulation technique. The breakthrough research could extend the capability of optical networks to meet surging data traffic demands.

"To go where no map has gone before"

"To go where no map has gone before"
A 3D sky-mapping project that will measure the light of millions of galaxies has received formal approval from the U.S. Department of Energy to move forward with construction. Installation of the project, called DESI (Dark Energy Spectroscopic Instrument), is set to begin next year at the Nicholas U. Mayall 4m telescope at Kitt Peak National Observatory near Tucson, Ariz., with observations starting up in January 2019.

Measure & validate optical fibres for astronomy

Molex has developed a Polymicro Technologies optical test bench to measure and validate optical fibres used in astronomy applications. The optical fibre measurement system measures Focal Ratio Degradation (FRD) in specific optical fibre samples to determine whether the fibres are appropriate for astronomy applications.

Fibre coupler suits CO₂ lasers

Fibre coupler suits CO₂ lasers
LASER COMPONENTS has introduced a fibre coupler for CO2 lasers, which transmits laser light and a pilot beam. The invisible light of CO2 lasers is often transmitted as a free-space beam with complex and expensive articulating optical arms used to guide the light to the required location. With the FiberKey P it is now possible for the first time to guide CO2 laser light in hollow optical fibres to any point and simultaneously transmit the light of a pilot beam.

Polarising fibres available for a range of wavelengths

Polarising fibres available for a range of wavelengths
Polarising fibres (PZ) only allow one polarisation of light to propagate along the fibre; the other polarisation will experience high losses. This is different to a polarisation maintaining fibre (PM) which will support propagation of both polarisations. PZ fibres have a specific waveguide design and a high birefringence so that the cut-off wavelength for the two polarisations is different. Coiling the fibre introduces higher losses for one of the polarisations so PZ fibres can be used to create a high extinction ratio ‘all-fibre’ polarisers.

Emulex Gen 6 fibre channel host bus adapters expands connectivity

Broadcom Limited has announced its family of Emulex Gen 6 Fibre Channel host bus adapters to address the demanding enterprise data storage requirements of flash storage arrays, virtualised and cloud datacentres. Data centres are rapidly deploying flash arrays to accelerate storage performance, but have ended up moving the performance bottleneck from the hard drive to the storage network.

Nanotech fibre technique lights up European industry

Nanotech fibre technique lights up European industry
A cost-effective method of fabricating high quality light-emitting fibres could benefit sectors ranging from sensors to wearable smart devices. EU-funded researchers have developed a new method for manufacturing fibres made from nanostructured organic materials. The breakthrough could lead to the cost-effective fabrication of light-emitting fibres at the nanoscale that can be used in sensors and bio-sensors, for energy harvesting (i.e. solar panels) and even in 'smart' clothing that can react to the environment.

Imaging with an 'optical brush'

Imaging with an 'optical brush'
Researchers at the MIT Media Lab have developed a new imaging device that consists of a loose bundle of optical fibres, with no need for lenses or a protective housing. The fibres are connected to an array of photosensors at one end; the other ends can be left to wave free, so they could pass individually through micrometer-scale gaps in a porous membrane, to image whatever is on the other side.
